(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 757) 9 Claims.

The invention described herein may be manufactured .and used by or for the Government for governmental purposes, Without the payment to me of any royalty thereon.

'I'his invention relates to a pouring apparatus.

The purpose of the invention is to provide a pouring apparatus which is particularly applicable to the rapid loading of a molten explosive into projectile bodies.

This purpose is accomplished -by means of a pan which is tilted to :cause molten explosive to flow into valve-controlled measuring containers before ybeing poured into the projectile bodies.

Further objects are to provide means for separately regulating the temperature of the pan and container so that there Will be no Iapprecibale change in temperature of the molten explosive as it passes through the apparatus and to so :arrange the v-alve that the valve stem may be employed to vary the capacity of the containers.

The specific nature of the invention as Well as other objects and advantages thereof will clearly appear from a description of a preferred embodiment as shown in the accompanying drawings in which:

Fig. 1 is la View in side elevation of the improved multiple pouring unit.

Fig. 2 is a view in rear elevation.

Fig. 3 is a sectional view through the pouring pan.

Fig. 4 is a plan View of the carriage.

Figs. 5 and 6 are detail sectional views taken on the corresponding lines o-f Fig. 1.

Referring to the drawings by characters of reference the carriage comprises an upper frame having side bars 5-5 and a plurality of cross bars 6. A plurality of upright brackets 'I on the upper frame each mounts a pair of rollers 8-8 which movably support the carriage from overhead I-beam rails 9. A shaft II) journaled in bearings II on the side bars carries a pair of pinions I2-I 2 each of which meshes with a rack I3 on the corresponding rail. The shaft is rotated by means of an endless chain I4 passing over fa sheave I5 iixed on the shaft. 1

Depending from each side iof the upper frame is an open side frame consisting of a vertical -bar IB and an angled bar I'I having an end extending beyond the vertical bar. The extending ends are connected by a cross bar I8.

A pan I9 has an angle bar 20 extending transversely across its rear side and a simil-ar angle bar 2| cn its front side but at a lower level. These bars project beyond the sides of the pan measuring and the projecting ends on the same side of the pan are connected by a side bar 22 which is spaced from the side Wall of the pan to provide accommodation for the bars I6 and Il of the side frame.

The pan is disposed Within the side frames |6-I'I--I8 and is tiltably mounted on trunnions 23 which are in the form of a headed bolt (Fig. 6) passing through the side har 22, through a bearing 24 in the angled bar I'I, and threaded in a reinforcing plate 25 xed to the pan. The trunnions are positioned n-earthe rear end of the pan so that the front end of the pan will normally drop until its cross bar 2I rests on the cros-s -bar i8 of the frame.

The mean-.s for tilting the pan comprises a standard air hoist 2B carried by the upper frame and having a double acting piston 2l with a pair of valve controls indicated at 23. The outer end -of the piston is attached to a cross arm 23.130- sitioned directly below the upper frame. A pair of cables .3U-35 attached to each end of the cross arm pass over sheave 3i carried by the frame and are connected` to a pin 32 (Fig. 5). The pin is carried by a .bracket 33 which i-s pivotally mounted on a .bolt 34 which is similar to the trunnion 23 and is mounted in an identical manner in the side bar 22 and reinforcing plate 25.

Referring to Fig. 3 the pan is double Walled to provide a-chamber or jacket 35 for a heating medium such las steam. The pan is shaped to provide Ia reservoir 36 at its front lower end iand it has a high rear Wall 3l providing a trough 38 which becomes operative when the pan is tilted so that molten explosive Will iioW over the :common lip 39. The pan carries a plurality of measuring containers 40 which are arranged in a row adjacent the lip 39 and which are normally in :a vertical position when the pan is resting on the frame prior to being tilted. The containers are surrounded by a steam jacket 4I Which is independent of the steam jacket of the pan. A steam jacket 42 attached to the under side of the jacket 4I encloses a plurality of pouring spouts 43, one being provided for each container.

through line 46 to jacket 42 of the pouring spouts.

Each container 40 is in fluid communication with its pouring spout 43 by means of a lbeveled opening 41 which may be closed by a valve 48. A valve stem 48a whose size may be altered tovary the capacity of the container extends upwardly through a plate 49 attached to a bracket 50. A spring i on each valve normally maintains it in closed position. A shaft 52 mounted in the bracket and rotated by means of a. handle 53 carries an actuating finger 54 Ifor each valve stem whereby the valves may be simultaneously opened.

Projectiles 55 which are to be lled with the molten explosive are placed on a stand 56 and are each provided with a funnel 51.

In operation the reservoir of the pan is nlled with molten explosive and the valves 41- are closed. The pan is then tilted about its trunnions by operation of the air hoist and the molten explosive in pouring over the lip 39 enters the measuring containers 40, the surplus being caught in the trough 38. The pan is then restored to its normal position, the Asurplus `explosive in the trough iiowing back to the reservoir. W ith the carriage in a position so that the pouring spouts are over a row of shells the handle 53 is actuated to open all of the valves and allow the measured quantity of explosive in each conviding a trough, a plurality of Vmeasuring coni tainers mounted in the rear wall and open to the trough, a jacket enclosing the containers, a pouring spout on the lower end of each container and having fluid communication therewith, a jacket enclosing the pouring spouts, a valve for` closing the lower end of each container and including a stem'extending upwardly through the container, means for actuating the valves, means for passing a heating medium through the jacketed members, and means on the carriage for tilting the pan on its trunnions. y
